Particle Sensor Using Solidly Mounted Resonators [PDF]

, 2015
This paper describes the development of a novel particle sensing system employing zinc oxide based solidly mounted resonator (SMR) devices for the detection of airborne fine particles (i.e., PM2.5 and PM10). The system operates in a dual configuration in

Bacteria detection with high-frequency gravimetric biosensors based on AlN thin film resonators [PDF]

, 2016
Gravimetric sensors based on shear-mode resonators are suitable for in-liquid detection of biological species because their quality factors barely decrease during in-liquid operation.

Experimental comparison of FBARs and SMRs responsitivities to mass loadings [PDF]

, 2012
The utilisation of thin film technology to develop film bulk acoustic resonators (FBARs) and solidly mounted resonators (SMRs), offers great potential to outperform the sensitivity and minimum detection limit of gravimetric sensors. Up to now, the choice

Analysis of spurious peaks at series resonance in solidly mounted resonators by combined BVD-Mason modelling [PDF]

, 2023
Solidly Mounted Resonators (SMRs) for high frequency RF filters and sensing applications often display spurious resonances that distort their frequency response.

Low-thickness high-quality aluminum nitride films for super high frequency solidly mounted resonators [PDF]

, 2012
We investigate the sputter growth of very thin aluminum nitride (AlN) films on iridium electrodes for electroacoustic devices operating in the super high frequency range. Superior crystal quality and low stress films with thicknesses as low as 160 nm are
